Contributions of the Fragile Families and Child Wellbeing Study to Child Development

We describe the promise of the Fragile Families and Child Wellbeing Study (FFCWS) for developmental researchers. FFCWS is a birth cohort study of 4,898 children born in 1998–2000 in large US cities. This prospective national study collected data on children and parents at birth and during infancy (age 1), toddlerhood (age 3), early childhood (age 5), middle childhood (age 9), adolescence (age 15), and, in progress, young adulthood (age 22). Though FFCWS was created to understand the lives of unmarried parent families, its comprehensive data on parents, children, and contexts can be used to explore many other developmental questions. We identify six opportunities for developmentalists: ( a) analyzing developmental trajectories, ( b) identifying the importance of the timing of exposures for later development, ( c) documenting bidirectional influences on development, ( d) understanding development in context, ( e) identifying biological moderators and mechanisms, and ( f) using an urban-born cohort that is large, diverse, and prospective.

Associations between Socio-Economic Status and Unfavorable Social Indicators of Child Wellbeing; a Neighbourhood Level Data Design

Background: Living in deprivation is related to ill health. Differences in health outcomes between neighbourhoods may be attributed to neighbourhood socio-economic status (SES). Additional to differences in health, neighbourhood differences in child wellbeing could also be attributed to neighbourhood SES. Therefore, we aimed to investigate the association between neighbourhood deprivation, and social indicators of child wellbeing. Methods: Aggregated data from 3565 neighbourhoods in 390 municipalities in the Netherlands were eligible for analysis. Neighbourhood SES scores and neighbourhood data on social indicators of child wellbeing were used to perform repeated measurements, with one year measurement intervals, over a period of 11 years. Linear mixed models were used to estimate the associations between SES score and the proportion of unfavorable social indicators of child wellbeing. Results: After adjustment for year, population size, and clustering within neighbourhoods and within a municipality, neighbourhood SES was inversely associated with the proportion of ‘children living in families on welfare’ (estimates with two cubic splines: −3.59 [CI: −3.99; −3.19], and −3.00 [CI: −3.33; −2.67]), ‘delinquent youth’ (estimate −0.26 [CI: −0.30; −0.23]) and ‘unemployed youth’ (estimates with four cubic splines: −0.41 [CI: −0.57; −0.25], −0.58 [CI: −0.73; −0.43], −1.35 [−1.70; −1.01], and −0.96 [1.24; −0.70]). Conclusions: In this study using repeated measurements, a lower neighbourhood SES was significantly associated with a higher prevalence of unfavorable social indicators of child wellbeing. This contributes to the body of evidence that neighbourhood SES is strongly related to child health and a child’s ability to reach its full potential in later life. Future studies should consist of larger longitudinal datasets, potentially across countries, and should attempt to take the interpersonal variation into account with more individual-level data on SES and outcomes.

Re-thinking Stepfathers’ Contributions: Fathers, Stepfathers, and Child Wellbeing

Using data from a contemporary cohort of children, we revisit the question of whether children benefit from being close to and engaging in activities with a stepfather. We deploy the Fragile Families and Child Wellbeing Study, a birth cohort study of nearly 5000 children born in US cities in 1998–2000, with a large oversample of nonmarital births. We explore the relationships between stepfathers’ closeness and active engagement and youth’s internalizing and externalizing behaviors and school connectedness at ages 9 and 15 for between 550 and 740 children (depending on the wave) with stepfathers. We find that the emotional tenor of the relationship and level of active engagement between youth and their stepfathers are associated with reduced internalizing behaviors and higher school connectedness. Our findings suggest that stepfathers’ roles seem to have evolved in ways that are more beneficial to their adolescent stepchildren than was previously the case.

Long-term research impact: the case of adolescents having ‘good places to spend free time’ in Ireland

Background Demonstrating long-term impacts of research can be fraught with methodological challenges, especially when approached retrospectively. Potential accusations of bias or over-interpretation, and a lack of clear and specific causal data, can be real obstacles. This paper presents a case study of research impact, including enablers and context to aid interpretation. To develop a national set of child wellbeing indicators in line with UNCRC commitments, a participative study of children's understandings of wellbeing was undertaken to accompany a Delphi study with experts. The children contributed a number of unique indicators, including having ‘good places to spend free time'. Methods Public actions which aimed to meet Irish commitments to child wellbeing were documented. Collected evidence comprised the development of, and reporting on, a national set of wellbeing indictors for children, the development and implementation of two national policies and cyclical monitoring data, collected through the nationally representative data sets of the Health Behaviour in School-aged Children (HBSC) study in Ireland, 2002-2018. Results Measurement of stakeholder-informed indicators helped stimulate national policies on play (2004) and recreation (2007). Partnership-based policy implementation led to increases in spaces for play and recreation. Trends data from the HBSC study revealed significant and meaningful increases in ‘good places to go spend free time' for children aged 10-17 from 45.1% in 2002 to 63.5% in 2018, and for all socio-demographic sub-groups. Temporal analyses showed that increases followed policy implementation. Conclusions This impact case study links an original participative study, though policy development and implementation, to long-term improvements in Irish children reporting having ‘good places to spend free time'. An understanding of the decision-making context at key points is important to aid interpretation of the evidence under investigation. Key messages Commitment to child participation influenced national indicator adoption, policy development and implementation, with subsequent improvements to children’s health-related environments. The quality and specificity of data needed to demonstrate long-term research impact is challenging and interpretation requires contextualisation to avoid leaps of faith.
